3 Claims.

Our invention is a device for the purifying of oil, and specifically the purifying of lubricating and fuel oils in servicing internal combustion engines. j

Some o f our main objects are a simple, economical, eicient, universally adaptable and changeable device of the character herein set forth.

Another object is a filter which first removes from the impregnated oil the heavier foreign ingredients prior to the treatment of the freed oil by a filtering medium.

A major object is a filter which can be mounted or demounted instantly for cleansing or renewal by the most unskilled, without tools or separate equipment.

Another major object is a filter which automatically discharges ingredients therefrom which have been separated out of the oil in process of purification.

Allied objects will appear.

Fig. 2 is a plan view of the sump portion of the filter taken along the line of the arrows 2-2 in Fig. 1.

Fig. 3 is a plan elevation of Flg..l with a portion of the headblock cut away showing inlet and outlet channels 'and a pressure control therebetween.

Fig. 4 is a sectional elevation of a modified form of the sump taken along the lines 2 2 of Fig. 1.

Fig. 5 is a plan view of the sump taken along the arrows 5-5 of Fig. 4.

Fig. 6 is a further modified form of a broken away portion of the sump 28. Fig. 7 is an enlarged cross section of an automatic sludge discharge.

As illustrated the device consists basically of three self-containedmembers, 5 being a headblock, 6 beinga filtering member, and 1 a locking bolt, making a unit assembly. On a face portion of the headblock 5 there are two concentric channels coaxially positioned with the locking bolt l and the axial tube 25 in the container 6. The channel 8 being a semi-circular incision directly associated with the inlet I5 and the channel incision 9 directly connected with the outlet I6. I is a head member fixedly positioned in the top of the container 6, the face of which has a pair of concentric channel incisions adapted to co-act with the incisions in the face (Ol. 21o- 140) plate of the headblock completing a pair of circular channels. Il is an inlet channel in the headpiece I0 co-acting with the channel 8 in headblock 5; I2 is a transverse constricted bore through I0 connecting II with tubel 25. I3 is a channel incision in block I0 complementary to and co-acting with channel 9 in block 5, I4 being a transverse bore through I0 co-acting with the channel formed of 9 and I3 and forming an outlet from the container 6 into channel I6; Ilia being an oil outlet through' the headblock 5 back to the engine. A pressure control I1 is projected between the inletl channel I5 and the outlet channel I6, Ila being the entry-port and ball seat for a ball I8, tensioned by spring I9; with anadjustable valve member this pressure control being a means of determining the pressures desired to be maintained within the filter. 2| is a glass member, one being seated over each channel I5 and I6 respectively adapted to view 20 the condition ofthe oil passing into and out of thev filter, the said glass being held in position by a nut 22, having an aperture 23 therethrough for a vision. I4 is a `passage in the container head I0 communicating with .the filtered oil space in the container 6.y 25 is a large central chamber inthe container 6 provided as vav quiescent settling chamberextending from the top of the container whereinto flows the fine stream of oil from the constricted inlet I2; this tube 25 30* is adapted to cau'se'the settling ,out or extraction by gravity 'of heavier impurities prior to the passing of the lighter portions of the oil upward through the filtering element 3I--3'l (inclusive). 26 is a sump for the depositing therein from tube 25 of heavier ingredients carried by the oil and which are intended to be deposited in the sump by gravity. 21 is a baille seatedv in the sump 26 and is adapted to quiet the heavier portions of the oil against agitation. 28 is a clearo ance below the balile 21 providing an outlet passage for that which is deposited in the sump. 29 is a disc divider projected adjacent the lower end of the oil tube 25 and adapted to direct the oil iiow outwardly; 29a is a modified form of the disc `divider 29. 30 is a perforated screen located in the top of the container 6 and adapted to provide a purified oil space, Aand is associated with the outlet I4 in the block I0 of the container; 3l is a more or less amorphous mass of filtering material which may be of such pre-determined' density as desired, there may be a sepa-l rating medium through a divider 32 from a further mass 33 of' a predetermined density, there being divisions 34 and 36 permitting predetermined densitiesin Il and l1, and also permitting the use oi diiierent types of material, comprising as an" entirety iiltering elements within the container 6:' these dividers being oi such material as will help to support the nltering material against collapse and being further designedto overcome channeling for the fluid in the operation of the illter. 3l is a perforated conical screen adapted to support the ltering material and provide a clear protective area for separating the denser portions ofA the iluid from its lighter portions, and this screen is centrally supported against the tube 25 by a ring 38a.' 39 is a threaded outlet from the sump 26; 40 is an automatic release having a channel 4I to a ball seat 42 in a channel 43, there being a ball 44 tensionally held against the ball seat 42 by a spring 45; said spring 45 being tensioned by a nut 46 which nut has an aperture 41 therethrough adapted to permit the passage of material being forced out by pressure and weight of the sludge from the sump 26;. 48 is a plurality of channels around the channel 43 and tributary theretoadapted to provide additional passage for material being forced out oi sump 28. ,4

In a modified form we show a pet-cock 49 manually manipulatable, seated in the outlet 39 of the sump 2B; and in a further modified form I-show a simple needle valve 50 manually ,l operable.

versal, any size oi' ltering element to accommodate any ltering demand can be installed on the universal headblock in a moment by simply turning a locking bolt. 'I'he oil feeding in .gkthe headblock practically subsides when the engine is not in operation, leaving practically no oil in the headblock between the oil-sights and the filter element, hence no loss of oil by changes and no filth nor uncleanliness.

It will be further observed that on dismounting the filter unit it can be immediately cleansed of its undesirable ingredients precipitated out of theoil into the sump whereupon the illter element can be replaced for new service ad innitum. In this connection, it will be observed this device overcomes all expense of service, all necessity for changing oil, or sacriilcing of the oil from the crankcase, maintaining its purity at all times. The impregnated oil from the crankcase is projected downward, precipitating by gravity into the sump ingredients heavier than oil, thereby passing the lighter freed oil up into and through the filtering material.

It is to be noted that neither skill nor ingenuityis involved in mounting or dismounting the filtering element; -for it is practically impossible to err as -the truncated cone on the. iiltering element head immediately enters the conical axis in the headblock. and-this conical axis-is the axis of the concentric circles. containing the oil flow connection.

We claim: e

l. An oil purifier comprising a headblock containing two channels i'or transmission of oil from and to an engine, said headblock having upon one surface thereof two concentric channels, each of said concentric channels communicating with one of said iirst mentioned channels, a cartridge member having upon its upper surface two .concentric channels which lare adapted to register with the concentric channels ci.' said headblock, and having an inlet channel of relatively small diameter communicating at one end with one of said concentric channels. and at the other end with a tube forming a vertical chamber within said cartridge member of relatively l large diameter, a sump in the bottom portion of said cartridge member into which said vertical chamber discharges, a horizontal baille member in said sump located beneath the end of said and means engaging said headblock and said cartridge member axially of the concentric channels of both elements for securing the cartridge member to the headblock.

2. A device in accordance with claim 1 wherein -the sump of the cartridge member is vprovided with a drain outlet, an outwardly facing seat in said drain outlet, a valve seated upon said seat, and a spring holding said valve in engagement with said seat against the internal pressure within said sump. A

3. A device in accordance with claim 1 wherein the sump is provided with a'plurality oi' vertical bailles, said banles being vradially positioned about a point beneath the end ofA said vertical chamber.
